'0 all whom it may concern:

Be it known that 1, JOHN VVnNznL, subject of the King of Hungary,residing at 235 est Sixty-fifth street, New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Dumping-lVagons, of which the following is aspecification.

This invention relates to unloading inachinery and has special referenceto devices for unloading vehicles of the coal wagon type.

The principal object of the invention is to provide an improved andsimplified mechanism of the type described and for the purposespecified.

The second object of the invention is to provide improved means forelevating the front of a wagon body while the rear thereof remainssupported by the frame.

A. third object of the invention is to provide improved means forelevating the body, after angular adjustment with relation to the framewhile at the same time retaining such angular adjustment.

A fourth object of the invention is to pro vide improved means forreturning the body to normal position after unloading.

A fifth object of the invention is to provide improved means forregulating and controlling the downward movement of the body.

With the above and other objects in view the invention consists ingeneral of certain novel details of construction and combination ofparts hereinafter fully described, illustrated in the accompanyingdrawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and

Figure 1 is a side elevation showing the frame and a portion of the bodywith the latter in raised position. Fig. 2 is a partial plan with thebody removed and showing the parts when the body is lowered. Fig. 3 is afront elevation of the body and frame, the former being in partly raisedposition. Fig. at is a longitudinal section on line of Fig. 3 showingthe body raised. Fig. 5 is a similar view showing the body lowered. Fig.6 is a perspective of the bars which support the body when raised. Fig.7 is a detail elevation of the rear end bar arrangement. Fig. 8 is adetail section showing the chain anchor or look. Fig. 9

a detail of the controlling brake. Fig. 10 1s a perspective of one ofthe bearings for thesupporting bar journals. Fig. 11 is a detailperspective of a certain trip used herewith.

In carrying out this invention there is provided a main wagon frame 1upon which are mounted cross bars 2 and extending longitudinally fromone of these bars 1 to the other are beams 3. F astened to the innersides of the beams 3 at the lower edges thereof are angle iron rollertracks 4. Secured to the under side of each beam 3 is a bearing 7 and inthese hearings, is j ournaled a shaft 8 whereon is fixed a gear 9 whichmeshes with a pinion 10 mounted on a stub shaft 11 and connected to agear 11. This gear 11 meshes with a pinion 12 fixed on a stub shaft, thelatter being provided with a squared end 13 so that a crank may beapplied thereto and thus move the entire gear chain. In order to supportthe outer ends of these stub shafts the beam 3 has secured thereto aplate lt in which the inner ends of the stub shafts are journaled andthis plate has secured thereto a D-bar 15 in which the outer ends ofsaid stub shafts are journaled. On the last mentioned beam 3 is provideda pivot pin 17 whereon is mounted a pawl 16, the end of said pawlengaging the teeth of the pinion 12 to prevent back motion of thegearing. This pin 17 also serves the purpose of securing one end of abrake band 19 which passes around a brake drum 18 revolving with thepinion 12 and preferably integral therewith. The other end of this brakeband 19 is attached to a brake lever 20 suitablypivoted on the beam 3.

Secured to the shaft 8 and wound thereon are chains 21 which have theirfree ends connected to V-shaped links 22, the latter being connected bystraps .23 to a shaft 2a. This shaft 24: is provided at its ends withrollers 25 which move upon the tracks 4-. Upon this shaft are alsopivoted the ends of certain bars 26 which have their opposite endspivoted, as at 27, to the body 28. On the rear cross bar 2 are mountedpivot supports 30 in which is pivoted one end of a bar 29, the remainingend being pivoted to a pivot or joint 27. Pivoted to the body 28 at 31are bars 32 which have their opposite ends revolubly mounted on a shaft33 carrying rollers 34. which roll along the bars 4:. This shaft 33passes through the slots 37 of yokes 86 which are connected by reachrods 35 revolubly mounted on the shaft 24L. Pivoted to each of the bars35 is a dog or latch 38 and on each of these dogs is a catch 89 which isarranged to contact with a trip 5 secured to the respective beam 3.

In order to hold the body against displacement by citing there areprovided manually releasable hooks 40 which are arranged to engage pins6 on the beams 3 when the body is lowered.

The operation is as follows: The shaft 8 is rotated by turning the crankand the chains 21 draw the shaft 2d rearwardly. Owing to the fact thatthe rear ends of bars 29 are stationary the point 27, when acted upon bythe bar 26 must move upwardly carrying with it the body-frame 28, and atthe same time slotted bar 35 is moving rearwardly, causing the beveledrear ends of the dogs 38 to ride upon the shaft at the exact moment whenthe front ends of slots 37 come in contact with shaft 33, the dogs 38drop over it for a purpose to be mentioned later, and until this moment,the angle of adjustment has been steadily increased, the rear end of thebodyframe remaining resting upon the rear end of the main frame, butafter the front ends of the slots come in contact with the shaft 33, thesaid shaftis pushed rearwardly, and the bars 32 carry the body-frame inthe same direction, at the same time carrying the body upwardly therebyequalizing the tendency of bars 26 to change the angle of ad justment.When the dog or pawl 16 is rc leased the pressure due to weight of thebody carries the rollers 25 forward, and as the bars 35 are on the sameshaft with rollers 25, the shaft 33 is also drawn forward by reason ofthe engagement with said shaft of dogs 38. The catch 89 rides over trip5 and lifts the dog 38 from shaft 33 at the moment the rear end of thebody-frame touches the main frame thus allowing the slot-ted bars freemovement forwardly, the transversely bent ends of catches 39 fallingupon the top edges of elongated portion 36 and limiting the downwardmovement of dogs 38.

Having thus described the invention, what is claimed as new, is

1. The combination with a vehicle frame; of a body frame, links eachhaving one end pivoted to the vehicle frame and the other end pivoted tosaid body frame, other links arranged. in pairs and each having one endpivoted to the body frame and the other end movable longitudinally ofthe vehicle frame, means to first move one pair of said links and thenboth pairs thereof, and pivoted 'hook members for locking thelongitudinal movable ends of said links together.

2. The combination with a vehicle frame; of a body frame, links eachhaving one end pivoted to the body frame and the other end pivoted tothe vehicle frame, tracks carried by the vehicle frame, a pair of linkseach having one end pivoted to the body frame, the other end of each ofthe last mentioned links being provided with a roller resting on saidtrack, a second pair of links arranged similarly to the last mentionedpair, shafts connecting the roller of each pair of links, yoke barspivoted to the forward shaft and having slotted ends engaging around therear shaft, chains connected to the forward shaft and extendingrearwardly, a winding drum around which the free ends of said chains arewound, and means to releasably hold the rear shaft in the forward endsof the yoke bar slots.

3. The comlinnation with a vehicle frame; of a body frame, links eachhaving one end pivoted to the body frame and the other end pivoted tothe vehicle frame, tracks carried by the vehicle frame, a pair of linkseach having one end pivoted to the body frame, the other end of each ofthe last mentioned links being provided with a roller resting on saidtrack, a second pair of links arranged similarly to the last mentionedpair. shafts connecting the roller of each pair of links, yoke barspivoted to the forward shaft and having slotted ends engaging around therear shaft, chains connected to the forward shaft and extendingrearwardly, a winding drum around which the free ends of said chains arewound, and means to relcasablv hold the rear shaftin the forward ends ofthe yoke bar slots, said means coinprising a pair of latches carried bythe yoke bars and arranged to engage the rear shaft when the yoke barsare moved rearwardly, arms fixed relative to said latch, and releasablecams carried by the vehicle frame and adapted to engage said arms andlift the latches as the yoke bars move forwardly.

In testimony whereof I aflix my signature in presence of two witnesses.
